javascript与php时/分/秒与秒数互转

1. javascript：

   /*
   时间转换成秒
   */
   function time_to_second(time){
   var arr = time.split(':')
   var hour = arr[0]?arr[0]:0
   var minute = arr[1]?arr[1]:0
   var second = arr[2]?arr[2]:0
   var ret = hour * 3600 + minute * 60 + second
   return ret
   }
   /*
   秒转换成时间
   */
   function second_to_time(seconds){
   hour = Math.floor(seconds / 3600)
   minute = Math.floor((seconds - hour * 3600) / 60)
   second = seconds - hour * 3600 - minute * 60
   if(hour < 10){
       hour = "0" + hour
   }
   if(minute < 10){
       minute = "0" + minute
   }
   if(second < 10){
       second = "0" + second
   }
   ret = hour + ':' + minute + ':' + second
   return ret
   }
   // var time = "10:00:00"
   // var ret = time_to_second(time)
   // console.log(ret)
   var seconds = 36000
   var ret = second_to_time(seconds)
   console.log(ret)

2. php：

   <?php
   /*
   时间转换成秒
   */
   function time_to_second($time){
   if(!$time){
       $ret = 0;
   }else{
       $parsed = date_parse($time);
       $ret = $parsed['hour'] * 3600 + $parsed['minute'] * 60 + $parsed['second'];
   }
   return $ret;
   }
   /*
   秒转换成时间
   */
   function second_to_time($seconds){
   $hour = floor($seconds / 3600);
   $minute = floor(($seconds - $hour * 3600) / 60);
   $second = $seconds - $hour * 3600 - $minute * 60;
   if($hour < 10){
       $hour = "0{$hour}";
   }
   if($minute < 10){
       $minute = "0{$minute}";
   }
   if($second < 10){
       $second = "0{$second}";
   }
   $ret = "{$hour}:{$minute}:{$second}";
   return $ret;
   }
   // $time = "01:00:00";
   // $ret = time_to_second($time);
   // echo $ret;
   $seconds = 3600;
   $ret = second_to_time($seconds);
   echo $ret;
